MACHINE-FOR RIVING, PLANING, AND JOINTINGSHINGLES.

Specification .of Letters Patent No. 345, dated June 15 1837.

To all whom t mag/.concern specifica-tion.

A, represents the frame of the machine, made of Asuitable size andstrength to contain and support :the several parts of .the machine,hereafter described; B, the car riage upon which the vshingle bolt C ismade fast, moving horizontally in grooves in the sides of way-s D, bymeans of a rack E, on

theisame in which works `a pawl F'attached to a lever, G, worked by thevertical ymovement ,of .the riving-gate H, hereafter described, by stops.or pins inserted therein; I, .clamp and screw for securing the :bolt tothe carriage; K, screw'for elevating or depressing the rear ends of theways in order to set .the bolt in a proper position to be cut intoshingles; L, fender posts of the riving gate; AM, riving gate .to which.the riving knife .is secured; N, riving knife; O, keys for inclining.the fender posts, so as to give the knife a. greater .or less endinclination.

in order to shave the face of the bolt in splitting loff .the shingle;P, pitman-rod which connects the lower end of the riving gate to thewrist of a crank-shaft which is turnedv by any convenient power; Q,inclined shaving table on which the shingle, when riven is shaved. Thisis of any convenient length, breadth, and thickness placed, and securedat an angle of .about 45, having also a transverse inclination of about10Q. The transverse inclination is wfor turning the shingle onto theedging table, hereafter described, placed at the end of the shavingtable. R, R, wedge-shaped or triangular ways, or guides, over which theshaving gate moves for shaping the shingle, said ways having the sameshape as the required shingle being raised or lowered by screws, to suitany thickness of shingle to be made; S, grooves in the sides of theshaving table in which move right angled tongues or hooks for keepingdown and guiding the shaving gate in its alternate backward and forwardmovement over the shaving table; T, a channel in the top of one of theways to admit a'cord or chain attached to .a slid- .ing fender board forreceiving and conveying away the shavings, `and the other Vendto asprlng `or weight on the frame, for ,drawing it back; U, a springstopplaced at the lower end `of the table and against which the shinglerests while beingshaved. When the knife has passed through the shingle,and arrives at the end `of the table, this stop 1s made to fall `bymeans of cams on the sides of the shaving `gate pressing upon arms ofthe stop projecting over the .sides of the table, and when .the yknifereturns the stop is pressed up again Yby -a spring under it. V, the.shaving gate .to which the shaving knife is fastened; W, ,the .shavingknife for shaving .the shingle set obliquely, vor at right angles withthe gate, as vmay be preferred; X, the cams on the ,sides .of theVshaving gate, before mentioned, for v.pressing down the spring stop andsuffering l:the shingle to pass to the jointing table; Y, bearing rolleron the shaving gate for holding ldown the shingle while being shaved; Z,sweeps or rods for connecting the shav- `ing gate to a second crank ofthe .before vmentioned crank-shaft by which it .is moved alternatelybackward `and forward; a, ways or guides forgiving the :shaving gate arectilineal direction in its backward .and forward movement; b, an arm.attached to the shaving egate for pushing the shingles lthrough thejointin'g machine, hereafter described, for jointing its sides; c,jointing table extending from the ,flower end .of ,the shaving table andinclined at the same angle, but set a little lower than the latter; CZ,permanent side olf the jointing table in which are set obliquely one ormore jointing irons; f, a movable stock in which are placedcorresponding jointing irons to those just described for jointing theother side of the shingle; g, dovetailed cross-piece of said stockmoving transversely in a dovetailed groove in the table; lz, spring tokeep the movable stock against the shingles and to allow of itsaccommodating itself. to any width of shingle to be jointed; z', arm,attached to the movable stock and jointing table by joints to guide thestock.

The shingle bolt being secured on the carriage and the machine put inmotion, the bolt is brought up to the riving knife by means of the pawlattached to the lever working in the rack on the carriage, the leverreceiving its movement from pins in the drop through upon the `iointingtable.

riving gate striking the lever in its ascent, thus bringing forward thebolt the thickness of a shingle at every stroke of the machine. Theriving knife in its descent .strikes the bolt at an angle of about lo ormore which causes it to shave the face of the bolt as it splits off theshingle; the shingle thus split falls upon the shaving table and slidesdown until it is arrested by the spring stop. The shaving knife thenpasses through the shingle and it is thus shaped rand shaved. The upperfender board is moved down by means of a pin in the shaving gate comingin contact with another pin in Vthe fender boardthe weight attached tothe cord of the board rising at the same time-this Vleaves roomV in therear of the knife for the shingle to The cams, or curved boards on thesides of the shaving gate or frame depress the spring stop which suffersthe knife and shingle to pass as before mentioned; the shingle is forcedthrough between the jointing irons and jointed'on both sides. Theshavings pass over the fender boards above and the shingle Adrops downat the end of the jointing table. /Vhen the shaving gate returns theweight draws back the upper fender board to its former position.

The invention claimed by me, the said lWIoRRIsoN, and which I desire tosecure by Letters Patent, consists, in

The before described mode of riving, planing, andv jointing shingles, bysecuring the shingle-bolt to a horizontally sliding carriage, movedforward the thickness of a shingle at every stroke of the machine, bymeans of a pin Vin the vertically moving riving gate, raising a lever'toYwhich a pall working in the rack of the A,carriage is attached, thebolt being fastened by clamps and the carriage adjusted -by screws toany required angle for changing the position of the bolt, the positionof the riving gate being also changed by keys, for causing the rivingknife, in taking off a shingle, to leave the side of the bolt in asmooth state;

ythen causing the shingle to fall upon a gular ways, to pass through theshingle for f taking 01H a shaving and leaving its surface smooth, theshaving passing over a board attached to; the top of the sliding frame Imoved forward with the latter and leaving a space in the rear, for theshingle to fall through upon the inclined jointing table; by means ofcams on the sides of the sliding frame pressing down the spring stop,and thus liberating the shingle, which, from its gravity, slides onwardto the jointing table and jointing irons, between which it is forced bya band attached to the under side of the sliding frame, and its sidesare thus jointed-the shaving boardv being returned to its formerposition by cord, pulley and weight, the gearing'being of the ordinarykind such as is well known to mechanics, namely, a crank shaft, fromwhich extends a pitman rod to the riving gate for propelling it; andfrom the same shaft another connection with the planing and jointingframe, by which it is moved backward and forward.

The individual parts of this machine are not claimed as new; but onlytheir combination and arrangement, in the manner herein set forth, forproducing a machine for riv-k ENocH n. Monsisov.v
